Title: MUD PUMP AND VACUUM GAS EXTRACTION SYSTEM
Abstract:
Systems and methods for extracting hydrocarbon gas are characterized by: a degassing device (10, 60) having a degassing chamber (38, 64) defined within an outer housing (36, 62); a mud inlet valve (44, 66) through which hydrocarbon-bearing drilling mud is flowed into a mud chamber portion (56, 92) of the degassing chamber; a degassing member retained within the degassing chamber and movable therewithin to expand the mud chamber portion of the degassing chamber, wherein hydrocarbon gas is extracted from the hydrocarbon-bearing drilling mud as the degassing member is moved within the degassing chamber; and a gas suction valve (50) for removal of extracted hydrocarbon gas from the degassing chamber.
